Intel Hyper-Threading?

[Bill Crocker]

Anyone running XP Pro on a system with Intel Hyper-Threading enabled? I
have an HP Workstation x4000, with two Intel 2GHz XEON's, with
Hyper-Threading enabled. My task manager is now showing four
CPU's...awesome!

Uhm. Yes. It does that. heh
That is what HyperThreading is.

Are you actually using it? Do legacy applications take advantage of it, or
do they have to be specifically written for it?

Thanks,

It actually depends on the application, just like dual processors would.
Some older applications have actually reported performance hits with
hyperthreading. Overall, you will usually see a increase in performance,
just because things are being split among the two virtual processors.
